Working principle:
In high voltage silicon rectifier stack, the rectifier diode in each rectifier diode module is run in a series arrangement, in stable state
In the process will not because of press caused by damage；But electric current from forward direction into reversed dynamic process, due to each rectification
Diode parameters are different, the difference of especially Trr (reverse recovery time), and rectifier diode is caused to press serious uneven and lead
Cause damage.Such as two rectifier diode series connection, reverse recovery time is respectively Trr1, Trr2, and Trr1 < Trr2, two pipes electricity
Pressure is respectively u1 and u2, and total backward voltage is U；It is now assumed that electric current is positive and starts reversely, at this time u1=u2=0 when t=0；
As t < Trr1, there is u1=u2=0；As Trr1 < t < Trr2, there are u1=0, u2=U, when U is greater than single rectifier diode energy
When the maximum voltage of receiving (being more than breakdown reverse voltage), second rectifier diode damage, two poles of subsequent first rectification
Pipe damage；And so on, the principle of tens even several hundred concatenated rectifier diode damages is identical with this in high voltage silicon rectifier stack.
The two poles of the earth parallel connection Transient Suppression Diode of technical solution of the present invention each rectifier diode in high voltage silicon rectifier stack,
The clamp voltage of Transient Suppression Diode is between the operating voltage and breakdown reverse voltage of rectifier diode.When rectifying two poles
For pipe in normal work, Transient Suppression Diode does not influence the work of rectifier diode, but when electric current is from forward direction to reversed
It is inconsistent due to each rectifier diode parameter during switching at runtime, cause it to press imbalance；During this, have
Rectifier diode both end voltage is low (when voltage is low, Transient Suppression Diode is not involved in work), and some voltage is high, and (voltage is high
When the clamp voltage of Transient Suppression Diode, Transient Suppression Diode just participates in work)；When rectifier diode both end voltage is super
It is connected and is simultaneously absorbed instantaneously when having gone out the Transient Suppression Diode maximum clamp voltage of its parallel connection, in the Transient Suppression Diode short time
Higher-energy, can clamper live rectifier diode both end voltage, and the voltage at each rectifier diode both ends is forced to be redistributed, protected
Each rectifier diode is demonstrate,proved to work in safe voltage section.By selecting suitable Transient Suppression Diode clamp voltage, make
Clamp voltage is greater than rectifier diode normal working voltage, and is less than rectifier diode inverse peak voltage, and reaching does not influence electricity
Road works normally and protects the purpose of rectifier diode, and high voltage silicon rectifier stack is effectively prevent to fail.When the voltage at rectifier diode both ends
When higher and significantly larger than Transient Suppression Diode maximum clamp voltage, two or more transient state suppression can be used
Diode processed is connected, and because of the principle of series connection partial pressure, two or more Transient Suppression Diode cooperates, always
Clamp voltage be concatenated single Transient Suppression Diode the sum of clamp voltage, thus by the voltage at rectifier diode both ends
Clamper achievees the purpose that same protection rectifier diode in safe voltage section.
